Could the Internet Be Taken Down In 30 Minutes?
GhostX9 writes "Tom's Hardware recently interviewed Dino A. Dai Zovi, a former member of Sandia National Labs' IDART (the guys who test the security of national agencies). Although most of the interview is focused on personal computer security, they asked him about L0pht's claim in 1998 if the Internet could still be taken down in 30 minutes given the advances on both the security and threat sides. He said that the risk was still true."
By a nuclear war for example.

Actually, this is exactly what it's supposed to survive.
In 2002 4 or 5 of the 13 root servers were big news ... although we've come a long way since then, I think the integrity of the internet still depends on these things.
Every so often we get reports that the internet is a rickety old jalopy on it's last leg.
Given this impression and add to it the fact that the botnets seem to grow in tandem with the internet, I wouldn't be surprised to see an attack take her down in 30 minutes although I'm no expert. I think 30 minutes is a generous amount of time if one of the larger botnets turned its attention on the root servers for a DDOS attack. You'd have some fail overs and some courageous engineer might save the day but I'd put my money on the bad guys.
I would be surprised if it was down for more than 24 hours following that though.

A federally enabled Internet kill switch will place an Internet Off Button in the White House which can be used to instantly deactivate the Internet in case of an emergency, such as the plebes getting riled up. This bill, introduced to the Senate on April Fools, is expected to pass.
In 30 minutes?
You're doing it wrong.
Guy who works in security testing wants people to believe that the state of internet security is OMGcritical? Shouldn't this be tagged "jobsecurity" rather than "security"?
All it would take is the right cables to be cut for the internet to go down. Perhaps with a rented backhoe even.

Assuming a vulnerability is exploited in BGP, the internet would go bibi in a hurry. That's all our eggs in one basket, and it's a fairly rickety basket. There's still a lot of trust inherent in the BGP fabric and trust is a 4 letter word to anyone who deals with infrastructure security.

According to my parents and people in my office, the Internet is occasionally down for several hours at a time. Fortunately, they have the ability to reboot it when necessary.
When Pakistan decided to block youtube they inadvertently caused a global routing blackhole. The internet is built with the BGP routing protocol, which is based on trust. You trust that your peers will advertise correct routes. If they don't then you get misinformation like in the Pakistan/Youtube situation and it spreads, pretty soon everyone thinks going through Pakistan is the best way to reach youtube so all traffic (or almost all) goes there, then Pakistan simply drops those packets.
... at least for a little while.
Of course this was an accident, but a malicious attack could simply advertise lots of incorrect routes and hose up everything

"A memorandum published by the DoD in March 1982 declared
that the adoption of TCP/IP as the DoD standard host-to-host
protocol was mandatory and would provide for "host-to-host
connectivity across network or subnetwork boundaries."
Military requirements for interoperability, security,
reliability and [b]survability[/b] are sufficiently pressing to
have justified the development and adoption of TCP and IP in
the absence of satisfactory nongovernment protocol
standards."
Emphasis mine.

I have all my most important sites IP addresses written on Post It notes all over my wall.
Bring it!
Forced peering would lead to situations where the data flow could be tilted from one side to another. "Peering" requires relatively equal data flow between the partners.
Take BGP for example. Very little security in it.
Sounds like somebody not involved in actual BGP work and/or just scaremongering (worship me because I say scary things).
Nobody configures their peers using dns addresses. Doesn't everyone use md5 hashes? Doesn't everyone filter their customers routes?
I did "most of" the customer side BGP at an ISP for "years" with quite a few customers... if every time someone redistributed 0/0 or 10/8 to us we took down the internet, frankly, it would have been down most of the time. Not to mention people whom thought their old providers IP space was their own (as opposed to actual ARIN space)
Then there's the guys who prepend like a hundred times, always good for a laugh or two.
Folks whom think they can take down global BGP by flapping their routes a couple times and don't even know what route dampening is... well...
Now, yeah, one bad dude could take over one router and maybe temporarily down one ISP that is run by fools who don't follow the "rules", but one badly run ISP out of bazillions is not "the internet".
Overall, I'd say out of 30K AS, of which at least 50% don't really know what they're doing, yet they still can't take the sucker down, god knows I've seen everything tried at least once, so a couple black hats don't even have a chance.

There's an awful lot of redundancy and inter-networking going on in the Internet, but a concerted attack at the right points in the Internet could take them offline, and break those links between networks.
No, it wouldn't cause your computer to blow up. It wouldn't break your home network. It wouldn't break your ISP's network. But if AT&T, L3, Verizon/UUNet, GBLX, Qwest, Sprint, etc. couldn't talk to each other, you'd as good as break the Internet. Remember the connectivity issues that were caused last year when L3 and Cogent de-peered each other? And those are relatively small players. Imagine if it were AT&T and UUNet that de-peered each other.
Somebody who knows the architecture of the Internet and *really* wanted to take it down wouldn't have a hard time at it. Just target the peering points between the big networks.
As others have pointed out, there's other weak points in the network, too. Gateway protocols and DNS are vulnerable to attack, as well, for example. :)

Yes, but where is the problem? A line doesn't need to be equially loaded in both directions. That's just a decision beancounters made. It doesn't make much sense in real life.
Just get a line between 2 ISPs and route only the trafic between those 2 ISPs on that line until it's full. The rest can go the long way.
ISPs should be forced to have to peer at any POP they join.
Forced to peer with spammers? no thanks!
Also "the internet" is mighty big. You might pull this off in one country, maybe the entire EU, but probably not the whole world. We (as a planet) can't even agree on basic human rights, much less the middle school girl game of whos gonna peer with who.

couple of very skilled and knowledgeable black hats with a severely huge and well-distributed botnet who were absolutely intent on taking down the entire Internet, could probably do so using multi-pronged attacks
Well, then we're getting into definition games. If 50% of the hosts on the net were infected and flooded the other 50% who were not infected/uninfectable yeah then something like that. You're going to have a huge task to find and flood every single BGP peer connection and flood all of them.
Also bear in mind that 99.999% of attacks are perpetrated by completely incompetent amateurs.
Yeah no kidding, and the folks whom do front line BGP support know it. I know it sounds rough, but in many cases it seemed the only difference between the black hats and the customers is the customers paid us money and were at attempting to do something productive.
Thing is, though, anyone with that much skill and knowledge would have far better things to do and would probably not benefit in anyway from bringing down the whole thing.
Unless they were a government hell bent on regulating it and controlling everyone/everything...

The real question is should the internet be brought down in 30 min.
A: probably so.

Oh, I don't know.. maybe it could have meant the ability to survive a single point of failure?
I'm pretty sure that not having a single point of failure was considered part of "reliability" even back then.
Maybe "forcing" is a bit strong, but ISPs should definitely be encouraged to do so. Every packet which does not go over centraliced portions of the net makes it more stable.
1) Maybe if I won't peer with him, he will hire me as an upstream and I'll make money. Extra funny if both sides try the same strategy. Even funnier if one side was recently paying the other, and now refuses and/or is going bankrupt.
2) My cheap router doesn't have enough memory/CPU/whatever to peer with EVERYONE at the IX, somebody is going to get cut. Or maybe I have the hardware, but the guy I'd like to peer with simply does not.
3) Maybe the IX charges $x for each peering connection (they gotta pay their bills somehow). So, if that peer is only worth $y of paid upstream traffic, and $x > $y, then ...
4) ISP "Y" does not have enough capacity outta the IX to handle the traffic I'd like to send them. (no one ever admits in public they are the ones whom don't have a large enough pipe to the IX, its always the other guys)
5) "X"-IX is just icky and flaps all the time and drops packets. Now that is good enough for our connection to Afghanistan Telco because we can blame the problems caused by the IX, on the satellite, but our customers will not tolerate those problems when connecting to skype, so no peering for skype at that IX! Bonus points if "X"-IX is on the other side of the planet from our techs, and/or their support sucks.
6) I'm secretly a middle school girl whom runs BGP at ISP "X" (sounds like an Anime series?). Now, I heard, that she said, that he read on the bathroom wall, that the middle school girl whom runs BGP at ISP "Y" said my network sucks, so ISP "Y" is soooooo off my myspace friends list and livejournal and AIM and also I'm not inviting them to my peering party. Now personally, I believe this scenario accurately represents about 99% of all peering disputes.
